To allwhom it'may concern:- 7

Be it known that I, FREDERIK JnNsnN, a citizen of the United States, and resident of Rochester, in the county of 'Monroe and State of New'York, have invented certain new and useful Improvements in 1 Fuel.- Tanks for Internal-Combustion Engines, of which the following a specification.

The present invention relates to fuel tanks for internal combustion engines and more particularly to the type in which provision is made for stopping the flow offuel from the tank when a certain level is reached in order to notify the user that the tank must soon be replenished, anobject of this invention being to provide an improved valve which is of simple construction and not liable to get out of order. A further object of the invention is to provide means which will prevent the opening of the tank to refill the same until the valve is shifted to a position where it will cause the fiow from the tank to cease before the tank is empty.

To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims- In the drawings:

Figure 1 is a fragmentary view of the tank in plan showing the means for locking the tank closure against removal in the position which it occupies when the valve is shifted to the position which causes the tank to cease to flow at a certain level;

. Fig. 2 is a View similar to Fig. 1 showing the closure locking means in the position which it occupies when the valve is turned to the position to empty the tank;

Fig. 3 is a fragmentary view partially in section showing the connection between the valve and the tank closure;

Fig. 1 is a detail view of the shaft which connects with the valve member;

Fig. 5 is a detail viewof the valve member;

Fig. 6 is a view partially in section of the valve casing;

Fig. is a side view of the valve casing; Fig. 8 is a top view of the valve casing; and

Fig. 9 is a detail view of the guide for the rod which prevents the removal of the closure. 7

Referring more particularly to the drawings 1 indicates the fuel tank which has an outlet pipe 2, in this instance threaded at its upper end in a bushing 3 secured to the bottom of the tank. The outlet pipe may be internally threaded to receive the lower threaded end 4 of a valve casing member 5. This valve casing member preferably is provided with a vertical passageway 6 extending therethrough and is also provided with a lateral port 7 leading to said passageway. In this valve casing operates a valve member 8, this valve member being preferablyprovided with a vertical passageway and with two lateral ports 9 and 10, one of said ports being in a higher plane than the other, the port 9 being elongated and receiving a projection 11 in the form of a screw passed through the valve casing and acting to limit the rotary movement of the valve member 8 by cooperating with the ends of the slot, this projection at the same time serving to support the valve member 8 in the valve casing 5. A rod 12 may be secured at 13 to the upper end of the valve member 8 and may project upwardly through the top wall of the tank 1, an arm or operating lever 14: being secured by a nut 15 to the upper screw threaded end of this rod 12. Through this arm the valve member 8 may be moved to open and close the port 7.

It is preferred to lock the closure16 for the tank 1 against removal until the valve member 8 has been moved to close the port 7 so that it will be impossible for the user of the tank to fill the same and then neglect to close the lowermost discharge opening. To this end, a bar 16 may be pivotally connected at 17 to the arm 14 and move in a guideway 18. This guideway may be formed by a single piece of metal secured to the top of the tank and bent between its ends to provide two loops 19 forming the guide 18 between them, the top of the guide being closed by one end 20 of the metal which is extended over the guideway and rests upon the upper ends of the two loops 19, the portion 20 being resilient and bearing on the rod 16 to produce friction thereon.

From the foregoing it will be seen that there has been provided in combination with a fuel tank, a valve in which a rotary valve member is provided with two ports, one of which is located above the other, the lower port being adapted to be brought into and out of register with the port in the Valve casing. There has also been provided a construction in which a projection cooperates with the lower part in the valve member to limit the rotary movement or the valve member. The invention also prevents the opening of the tank until the lower discharge opening of the valve is closed 'so that it will be impossible for the user of the tank to fill the same without first closing the lower discharge opening.

\Vhat I claim as lnv invention and desire to secure by Letters Patent is:

1. In combination with a fuel tank for internal combustion engines having an outlet; a rotary valve for controlling such outlet 1 comprising an open ended casing member having a lateral port, a valvemembermounted to turn in said casingprojecting from the upper end of the casing, having its lower end openinglto the open lower end of the casing in all positions of the valve and having also two'lateral ports, one above the other, the lower port being adapted to be brought into and out of register with the port in the casing member upon the rotation of the valve and means for limiting the rotary movement of the valve and preventing the longitudinal movement thereof.

2. In combination with a fuel tank for internal combustion engines having an outlet; a valve for controlling such outlet comprising a casing 'm'einber having a lateral port,v a valve member mounted to turn in said casing and having two lateral ports, one above theother, the lower port being adapted to be brought into and out of register with the port in the casing member, and a projection within the casing member, operating in the port of the valve member to cooperate with opposite end of the port inorder to limit the movement of the valve 7 member in said casing member.

3. In combination with a tank for internal combustion engines having an outlet, and an inlet, and a closure forthe inlet; a rotary valve for controlling such outlet, having a
